IMPROVEMENT IN APPARATUS FOR FINISHING TUMBLERS.

Specification forming part of Letters Patent No. 1 25,145, dated April2, 1872.

SPECIFICATION. To all whom it may concern:

Be it known that I, DANIEL G. RIPLEY, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, haveinvented a new and usefulImprovement in Finishing Tumblers, 82c. and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawing forming part of thisspecification, in which-- Figure 1 is a side elevation of my improvedmachine for forming or finishing tumblers or other like hollow articlesof glass-ware. Fig. 2 is a vertical sectional view of the same whenfinishing a tumbler. Fig. 3 is a. side view of the same, partly insection, modified so as to apply power to it. Fig. 4 is a like viewofthe former in a vertical position, in which it may be used Without afollower or tool and Fig. 5 is a view of a punty carrying a tumbler.

Like letters of reference indicate like parts in each.

I Heretofore tumblers and other like articles of hollow glass-ware havebeen finished by hand in the following manner: The tumbler having beenfirst pressed is carried by means of a purity to the glory-hole andheated. The punty is an iron rod, having on one end a lump ofsemi-molten sticky glass, which is put against the bottom of thetumbler, and to which it adheres, as shown in Fig. 5, in which a is thepunty a, the mass of semi-molten glass; and b, the tumbler. After thetumbler has been heated it is taken to a chair, whichhas long extendingarms, in which the workman sits, while with one hand he rolls thepuntyback and forth upon the arms, and with the other hand shapes andfinishes the tumbler by means of a wooden paddle called a buffer. Thisoperation requires time and skillful labor.

The object of my invention is to secure an easier, quicker, and cheapermethod of finishing tumblers and other like articles of hollowglass-ware, and this I do by the means hereinafter described andclaimed.

To enable others skilled in the art to make and use my invention, I willdescribe its conor burnished surface. Directly under the mandrel orformer e is a tool or follower, f, the inner face of which is smooth orplanishedl. The tool f is held in place loosely, so as to allow it tomove, by the screw g projecting through the slot h from the opposite ofthe disk d. Hinged to the lower end of the toolfis the arm t, which ispivoted to the projection k, and on its outer end carries a rest orsupport, I, for the punty a. The arm '5 actuates the tool f, the motionof which is limited by the slot h. When there is no pressure on theouter end of the arm 6 the weight of the tool f is suflicient to causeit to drop down to the lower end of the slot h, away from the former e.\Vhen there is sufficient pressure on the outer end of the arm 2' thetool f is forced up toward the former 6 until the screw encounters theupper end of the slot h, when the space between the former e and tool fis equal to the thickness of the sides of the tumbler to be finished.

The operation is as follows: The tumbler is carried 011 the punty, asshown in Fig. 5.

from the glory-hole, and is placed on the former 0, while the punty isrested upon the support I, as shown in Fig. 2. The weight of the puntyupon the outer end of the arm 2' forces the tool f up against theexterior surface of the tumbler. The punty" is then revolved by hand, soas to cause the tumbler to revolve two or three times between thepolished surfaces of the former and tool, which gives to it the roundshape required .more accurately and much more quickly than can be doneby hand. The tumbler is then removed to the sand-box in the usual way.

Fig. 3 shows a way by which power may be applied to operate the disk andformer, so as to make them revolve. In this case the tumbler is heldstationary,while being formed, by the revolving former and tool. Thestand 0 is extended up as at 0, so as to afford a bearing for the shaftm, which on one end carries the disk d, which is otherwise unconnectedwith stand 0. The arm 1' is rigidly attached to the stand 0, andsustains the support Z on its outer end. The tool f is attached to thedisk (I by the screw or bolt g in the slot h, and is actuated by aspiral spring, 12, which occupies the lower end of the slot, and pressesthe tool up against the exterior surface of the tumbler. The handle 0 isfor drawing down the tool f,

so that the tumbler may be placed on the-mandrel a with ease andquickness. plied to the shaft at either by a crank or by a foot-treadleextending forward, so as to be worked by the operator, or in any otherdesired or convenient way. Steam or other like power may be applied bythe use of proper devices to give a regular intermitting motion.

The operation is the same as that described, two or three revolutionsot'the former being sufficient to finish the tumbler.

The former 6 may be used with a hand-tool instead of the tool f,attached as shown in Figs. 1, 2, and 3.

It the former e is placed in a vertical position, as shown in Fig. 4, itmay be used witln out a tool; for the glass, beingin a soft plasticcondition, will conform to the shape of the former, and becoming chilledalmost immediately hardens, and retains the form thus given it. Thisoperation requires more care and skill than when a tool is used asdescribed, and the former must be of the exact shape to be given to thearticle.

The former and tool are made of any suita ble material, such as iron,steel, soap-stone, or wood; but in the latter case would have to berenewed very often, as it would be burned away by the heated glass.

The shape of the mandrel e, as used in Figs. 1 and 3, may be varied. Apin having a pol- Power is apished surface, properly placed-that is,placed a distance from the tool fwhen' at the extreme upper limit of itsmovement equal to the thickness of the edge of the tumbler, so that theedge of the tumbler could pass between would answer the purpose.

lVhat I claim as my invention, and desire to secure by Letters Patent,is

1. The mandrel or former e for shaping tum blers or othersimilarly-shaped hollow articles of glass-ware, either revolving whilethe tumbler is held stationary, or stationar Y while the tumbler isrevolved upon it, substantially as hereinbefore described.

2. A former or mandrel, in combination with a tool or follower forforming tumblers and other similar hollow articles of glass-ware, substantial] y in the manner described, either stationary while the tumblerrevolves between them, or revolving while the tumbler is heldstationary.

3. The combination of the arm 41 and the adjustable tool], for thepurposes described.

4.. The spring a, in combination with the tool f, substantially asdescribed.

In testimony whereof I, the said DANIEL (J. RIPLEY, have hereunto set myhand.
